Amorphous and nanocrystalline Iron(III) oxides from thermally induced solid-state reaction
Zbořil, R. ; Mašláň, M. ; Machala, L. ; Grygar, Tomáš
Iron(III) oxides presents as a unique polymorphic compound yielding the varied structural forms with different particle size and morphology depending on the preparation method.
Homogeneous precipitation with urea - general preparation method to obtain metal oxide nanoparticles
Šubrt, Jan ; Štengl, Václav ; Bakardjieva, Snejana ; Maříková, Monika
Heterogenous precipitation based on moxing of solutions of alkalis and soluble metal salts in aqueous media is commonly used method for preparing oxide-hydroxides of trivalent (Fe, Al, Cr) or tetravalent ( Ti, Zn ) metals.
The modern method analysis pointings
Bezdička, Petr ; Grygar, Tomáš ; Kučková, Štěpánka ; Hradilová, J.
Baseline identification of pigments is not sufficient for the description of technical style of painting and its authentication. Qualified interpretation of the stratigraphy of colour layers accompanied by the description of their microstructure is only able to help with the evaluation of origin and authenticity of the painting. Wide comparative database and close cooperation of scientists, restorers and art historians is always necessary. Diversity of forms, in which titanium occurs in nature, could be given as an example documenting the necessity of highly professional and sensitive approach to data within this research area.
